PRICE REGISTER FOR FLUID'DISPENSING Y APPARATUS This invention relatesto a price register for fluid dispensing apparatus, and moreparticularly to a price register including an improved variator of unitvolume price for thefluid. I

Conventional fluid dispensing apparatus, for instance apparatus forselling gasoline, kerosene, heavy oil, liquefied petroleum gas, and thelike, includes a register capable of indicating the amount of the fluidbeing dispensed. It is a recent trend to add'aprice register to the v iffluid dispensing apparatus, with the intention of providing customerservice and saving time necessary for manually determining the price ofthe fluid sold, which price register is interlocked with a fluid amountregister of conventional construction. The unit volume price of fluid,e.g.,gasoline, is usually variable. For instance, a

discount may be allowed for customers who regularly purchase but acomparatively clear fixed price may be changed for other customers. Ingasoline stations and other retail stores, it is generally desirable tomodify the According to the presentinvention, thereis provided a priceregister for fluid dispensing apparatus having 'a' means for varyingunit volume p'rice setting for fluid, comprising a gearing consisting ofa gear cone having coaxially dispo'sed'spur gears of different diametersand secured to an output shaft of aflow metermeasuring the flow rate offluid being dispensed by said apparatus;

a price indicator; at least one transmission shaft opera tivelyconnected to said price indicator and disposed in the proximity of saidgear cone and extending in parallel to axis of rotation of said gearcone; a carrierarm means connected to said transmission shaft in anaxially slidable and rotatable manner and carrying a transmission spurgear means which is selectively engageable one of said spur gears ofcone for transmitting the rota tion of said output shaft of said flowmeter to said trans mission shaft; a first carrier arm operating meansvertically reciprocating said carrier arm means along said transmissionshaft for selectively disengaging and re- 7 engaging said transmissionspur gear means relative to v one of said spur gears of said gear cone;and a second unit volume price depending on the sales and the type ofcustomers. If a price register calculatesand indicates theprice based ononly one-unit amount price, the

storekeeper has to separately'calculate the price when fever he sells toa customer to whom heallowed a discount. In practice, a typical gasolinestation has a wide variety of price per unit volume'of gasoline fordifferent customers, depending on the amount each customer mayre'gularly purchase'. Accordingly, there is a need for a price registerin a"fluid dispensing apparatus which register is readily"adjustablefordifferent unit volume prices.

. Another object of the present invention is to provide a price registerfor fluid dispensingapparatus, in which setting of unit volume price caneasilybe modified from theoutside thereof but such modification cannotbe effected once the fluid dispensing apparatus is made ready for fluiddispensing operation. whereby, the dan-- ger of gear breakage orotherda'rnages due to erroneous operationofunitvolume price modificationduring fluid dispensation is completely'eliminated.

pensed, for instance,to a vehicle/The flow meter-1'6" has an outputshaft 161 which rotates at a speed proportional to the flow rate ofliquid fuel being dispensed therethrough. A volume indicator 18 isdirectlydriven' by the output shaft l6l' oftheflow meter (FIG. 2),

whilea price indicator I8 is connected to the output shaft 161 throughapriee calculating mechanism 20 having a known calculating means. A knobor dial 201 is provided at the outside of the price calculatingmechanism 20, so as to actuate a means for varying unit volume price ofthe liquid fuel being dispensed, as will be described in detailhereinafter. The indication of the i volume indicator 1'8 and the priceindicator 18' will be I reset by operating a resetting lever 22.

3 FIG. 2 shows the detailed construction of the price calculatingmechanism 20. As pointed out in the foregoing, the output shaft 161,which is rotated at a speed proportional to the flow rate of the liquidfuel being dispensed, is directly connected to the volume indicator 18.The indicator 18 includes a suitable integrating means (not shown) forintegrating the flow rate information delivered from the flow meter 16,and indicates the total volume of the fluid fuel dispensed in a givendispensing operation. If desired, the volume indicator 18 may bereplaced with a flow rate indicator which indicates the instantaneousflow rate of the liquid fuel being dispensed. i A gear cone 24 iscoaxially secured to the output shaft 161 of the flow meter 16. In theillustrated embodiment, the gear cone 24 consists of 9 spur gearsoverlaid one on the other in a coaxial fashion. The diameter of eachspur gear in the gear cone is the largest at the bottom of the gear coneand the smallest at its top, while the-diameter varies gradually as thegear cone 24 extends downwardly. The gear cone 24 is described as beingmade-by overlaying a number of spur gears, but it is also possible toform the entire gear cone 24 as one .block from a unitary material. Aplurality of transmission-shafts 26 are disposed about the gear cone 24,of which only one shaft 26 is shown in FIG.2 for simplicity. Forinstancethree transmission shafts 26 may be used, so as to representthree different places of unit volume price of the liquid fuel: namely,digits of 10, 10, and 10 places or digitsof the orders of 1 cent, 10cents and l dollar, respectively. The three shafts maybe disposed alonga circle having a center on the axisof the gear cone 24. Eachtransmission shaft 26 is rotatable, with its top end being journalled bya cover plate 28 of the calculating mechanism and its bottom end beingpivotally supported by a supporting plate 30. Referring to FIGS. 2 and3, each transmission shaft ,e 26is provided with one end of a gearcarrying or holding'arm 32 mounted thereon in an axially slidable androtatable manner. The arm 32 rotatably carries two spur gears; namely, aspur gear 264 disposed coaxially with the transmission shaft 26 andanother. spur gear 321 which is kept as meshed with the spur gear 264.The spurgear 264'is rotatable relative to the arm 32 but'notrotatablerelative to the transmission shaft 26. As can bese'en from FIGS. 2 and3, th'e'spur gear 321 can'be'broughtinto operative engagement with oneof thespur gears of. the gear cone 24, in response to the rotation ofthearm 32 about the shaft 26.:Theparticular spur gear'of the gear cone24' to which'thegear 321 meshes dependsonthe vertical, position of thearm 32. When the spur gear'321 meshes one of the spur gears of the gearcone24', the rotation of the output shaft 161 of the't'low meter 16 istransmitted to the transmission shaft 26 through the gears 321 and 264.Another spur gear 262 is coaxially secured to the transmission shaft 26at an, upper part thereof. The gear 262 is operatively connected to anadder mechanism 34 of known construction through its input gear 341.Thus, the rotation of the transmission shaft 26 is given to the addermechanism 34, and the output from the adder mechanism 34' is applied tothe price indicator 18' through an output gear 342 of the addermechanism 34 meshing with an input gear 181" of the'indicator 18.,As aresult, the price indicator 18' provides an indication of the price ofthe liquid fuel for the amount being dispenced.

A comb-like plate 322 having a plurality of downwardly open notches 322ais secured to the other end of the arm 32, as seen in FIG. 2. In theillustrated embodiment, the comb-like plate 322 should'prefe'rably haveten such downwardly open notches 322a. The comb-like plate 322 has anarcuate edge with its center of curvatureat the axis of the shaft 26, asshown in FIG. 4

when the spur gear 321 meshes the corresponding one of the spur gears ofthe gear cone 24. 1

To selectively disengage the comb-like plate 322 from the bracket 301, acomb raiser 36 is slidably fitted on the upper end portion of thebracket 301, as can be seen from FIGS. 2 and 5. The comb raiser 36 isconnected to one end of a rocker arm 362through the supporting plate 30by a vertical link rod 361. The rod 361 may be aligned with the bracket301, as shown in FIG.

5, or offset from the bracket 301, as shown in FIG, 2

The rocker arm 362 is pivotally supported by a stud secured to a bottomplate 38 of the calculating mechanism 20. Referring to FIG. 2, theoppositeend' of the rocker arm 362 is connected to the resetting lever22 (FIG. 1) through a vertically reciprocating lever 363. The lever 22also acts to reset the indications of the indicators 18 and 18'. Atension spring 364 is wound about the link rod 361 at a portion betweenthe rocker arm 362 and the supporting plate 30.

When the resetting lever 22 is turned in aicounterclockwise directionfrom its position as shown in FIG. 1, the rod 363 is pulled up so as topull down the link rod 361 and the comb raiser 3 6'through the rockerarm 362. The tension spring 364 acts to assist such pulling down of thecomb raiser 36, so asto' keep the comb raiser away from the comb-likeplate 322. Then, as the resetting lever 22 is turned'in 'aclockwisedirectiomthe lever 36 3 moves downwards, so as to pushup thelink rod 361and the comb raiser 36 throughthe rocker arm 362 against thetensionspring364. As a result, the

comb-like plate 322 is pushed up by the combraiser 36 and removed fromthe-bracket 301.- I To turn the gear holding arm' 32 after raising thcomb-like plate 322, an' arm rotating means40 isprovided so as to turnthe arm about the longitudinal axis of the transmission shaft 26.'Itshould be noted that the arm rotating means 40 is rotatable relativetothe transmission shaft 26. The arm rotating-means 40 has its upper endsecured toa 'sleevedbevel gear 401 rotatably mounted on thecover plate28, and itslower end is se- 401, so as to allow themcans 40 to rotaterelative to the shaft 26. Upon turning the knob or dial 201 .(FIG. 1),

a link rod 202 is rotated so as to turn a bevel .gear 203 secured to theopposite end of the rod 202 to said dial 201. Consequently, theaforesaid'sleeved bevel gear 401 meshing with the bevel gear 203 isturned about the transmission shaft 26. Since the'ai'm rotating means 40is integrally secured to the sleeved bevel gear 401,

sition of the arm rotatingmeans 40. v

the actuation of the knob 201 causes the arm rotating means 40 to turnabout the transmission shaft 26.

- Referring to FIG. 4, each sector plate 402 has an ar- F I cuate edge,which includes a plurality of recesses402a corresponding to the notches322a of the comb-like plate 322. Moreparticularly," in the illustratedembodi- Q ment, l0 recesses 402a are formed on the sector plate402,"each corresponding to one of said notches 322a of the comb-likeplate 322; A roll 42 carried by a suitable lever is biased by a spring44 toward the arcuate edge 'ofthe sector plate 402, so as to operativelyengage one ofthe recesses 402a for indexing the angular position of thesector plate402, and accordingly the angular po- FIG. 4 illustratesalink rod 46 which transmits the rocking motion of the rocker arm 362 toall the comb raisers 36 of the price register.

the notches 322a of the plate322 are all freed from the top edge of thebracket 301, so as to allow the plate 322" and accordingly the gearcarryingarm 32 to turn about theaxis of the transmission shaft 26.--Whenthreetransmission shafts 26are used for representing three digits I oftheunit'volume price'of-theliquid fuel, e.g.,'digits of 10', and 10places'or digits of the-orders of 1 cent, IOcents, and 1 dollar, allthegear carrying arms 32-for the three shafts 26 arefreedifor indexing.it is understood, that, for the three transmission shafts 26,three'setting knobs ordials 201"areprovided for independently, settingeach of the three digits of the unit volumepriceof the liquid fuel beingdispensed. A I I Accordingly, to begin with the operation of theprice Iregister of thepresent invention, the three knobs or dials'201'areturned,;for setting the gears 3'21 and the gears of the gear cone24,-which represent the desired digits atthe places of 109,10, and 10orat the places of 1 cent, l0ice'nts; .and 'ldollarnSuch setting of thecarf rier arms 32 is effected by the corresponding link levers 202 (orequivalent chains or wires) and the arm rotating means 40. Sinceeach ofthe sector plates 402 is indexed at the desired-one of discrete angularpositions by'the engagement of the spring biased roll 42 and thecorrespondingone of the recesses 402a, thecorre- ,sponding one of thenotches 322a of the corresponding comb-like plate 322isaccurately'indexed to a position engageable withthe top end of thebracket 301.

direction, the indications of the two indicators 18 and 18' are resetand the motordriven pump 12 is actuated.

At the same time, the vertical lever 363 is pulled up to its own weight,until the previously indeited notch 322a engagesthe top end of thebracket 301. After the indexed notch 322a has engaged thebrackct 301,the

knob or dial 201 is automatically locked by such engagement and itcannot be turned any more. Thercaf-- ter, upon actuation of the trigger(not shown) of the nozzle 162, the liquid fuel is dispensed through theflow meter 16 and the nozzle 162. Thus, the rotation of the output shaft161 of the flow meter 16 is directly transmitted to the volume indicator18, so as to provide the indication of the volume of the liquid fuelbeing dispensed. The rotation of the output shaft 161 of the flow meter16 is also transmitted to the three transmission shafts 26'through thegear cone 24 and the three gear trains each having two spur gears 321and264, so as tov rotate the three shafts 26 at the speed predeterminedorset by the knobs 201, relative to the revolving speed p i of theoutput shaft 161, The informations -represented by the rotations of thethree transmission shafts 26 are applied to the adder mechanism 34through three gear 7 separate the comb-likeplate 322 from thebracket301.; Thus, the gear carrying arms 32 and the spur gears 321 becomesready for new setting or indexingfby the knobs or dials 201, so as torepresent a new unit volume price.
